HAY- ELEVATOR.

SPECIFICATION forming part of Letters Patent No. 291,822, dated January 8, 1884 Application filed November 12, 1883.

To all whom it Hwy-concern:

Beit known that I, PHILLIP WERUM, a citizen of the United States, residing at Stryker, in the county of XVilliams and State of Ohio, have invented certain new and useful Improvements in Hay-Elevators; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention pertains to improvements in elevators specially intended for use in connection with horse hay-forks, having for its object, principally, to secure lightness and compactness of construction and insure certainty and facility of operation, whereby cheapness and salability of the article are promoted.

The invention consists of a car or conveyor, between the forward arms or within a space in one end of which is pivoted a bent or angular gravity-pawl, with one end of its tooth engaging a notch or stop of the inclined railor track upon which the car travels, while its greater portion, including that in the same plane as its fulcrum, is slotted or cast in a skeleton form.

It consists of further details of construction of the gravity-pawl and car, substantially as hereinafter fully described.

In the accompanying drawings, Figure 1 is a view in side elevation of my invention as ap plied for use. Fig. 2 is arear end view of the' carriage. Fig. 3 is a side and plan view of the gravity-pawl; and Fig. 4.- is an enlarged view of the carriage, partly broken away.

In the organization of my invention I employ a car, A, having no peculiarity of construction, only in the respects hereinafter mentioned, which, as usual, is contrived to travel on the incline track B, of common construction, said car having wheels a c traversing the rail or flange of the track. The forward edge of the bottom pieces of the car is beveled on its under side, as Z), the function of which will be presently seen.

0 is the gravity-pawl, of angular or bent form, and pivoted at its angle, between the forward arms of the car, (or it may be pivoted in a space in said end,) the shorter bent (No model.)

portion of said pawl constituting its tooth, which is caused by gravity or the weight of the longer unbent portion to rest against the under side of the rail and at the proper time to engage with an oblique notch, c, (or stop,) on the latter. The extreme forward end of the tooth of the pawl O is beveled on its upper edge, as at c, to insure certainty of action or engagement of the pawl with the rail or track. The forward edge of the bottom piece of the car being beveled, as above set forth, it will be seen that the fulcrum-point of the pawl can be placed nearer thereto without interference with the required movement of the pawl, to allow it to enter its notch in the rail or track than with a different construction of parts, thereby securing compactness and lightness of construction, less metal being required in casting the same. The pawl O is provided with a slot, 0, extending through its greater portion, including that in the same plane with and inside of its fulcrum, as shown in the plan view of Fig. 3, the purpose of which, as seen in Fig. 4, is to permit contiguity of arrangement of the forward pulley, D, with the pawl,

the requisite amount of space for the passage of the hoisting-rope E between the said pulley and pawl being wholly obtained by means of the slot G in the pawl and thegroove in the pulley, and still further promoting lightness and compactness of construction.

A counterbalancing-weight, F, is suspended from a cord or rope, E, connected to the rear end of the car A, and passed over a pulley, (I, supported at the lower end of the rail or track 13.

The operation of the machine is obvious, since it will be noticed that when the car is at or contiguous to the lower end of the rail, at which time the pulley-block, with the attached fork, is in a lowered position, the pulley-block will, upon being elevated into contact with the unbent portion of the pawl O, disengage the bent portion or tooth of said pawl from the notch c in the rail or track B, which will allow the car to be moved, with its load suspended therefrom by the fork, to its required destination.

The advantages of my improvement, having been fully incorporated in the foregoing, do not therefore need further reference or recapitulation here. i

I am aware that changes in details of construction of the parts composing my invention can be made without departing from the principle or sacrificing the advantages thereof. I would therefore have it understood that I do not limit myself to the exact construction herein shown and described, but hold myself at liberty to make such changes and alterations as fairly fall within the scope of my invention.

Having thus fully described my invention,

what I claim, and desire to secure by Letters Patent, is

1. In an elevator, the combination, with the ear, of the pawl O, pivoted between the forward pulley-arms of or within the car, and having a slot, 0, extending through its length, including that portion in the same plane and inside of its fulcrum, substantially as shown and described, and for the purpose set lorth.

2. In an elevator, the combination, with the car having the lower forward edge of its bottom piece beveled, as at b, of the angular or bent pawl O, pivoted between its pulley-arms, and having a slot, 0', extending through its greater portion, including that in the same plane with and inside of the fulcrum of the pawl, substantially as shown and described, and for the purpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.
